As a main game released in 1989, The Duel: Test Drive II is an arcade/simulator racing title where you drive exotic cars on varied, hazard-filled highways. The core loop involves reaching a gas station checkpoint quickly while managing traffic and avoiding police pursuits. Players choose difficulty, affecting transmission type, and must manage lives lost from crashing or running out of gas. Distinctive features include the option to race against a computer opponent instead of just the clock, and a standard radar detector for anticipating law enforcement.
The primary gameplay loop centers on navigating distinct, multi-lane highway courses featuring varied scenery, sharp turns, and environmental hazards such as bridges, tunnels, and cliffs. The ultimate goal for each level is to reach the designated gas station at the end of the course in the least amount of time. Failure to stop at the gas station results in running out of fuel and losing a life.
Players begin the game with five available lives. Collisions with other traffic or off-road obstacles deduct a life and add a thirty-second time penalty to the overall score. Furthermore, players operating a manual transmission risk engine failure by "redlining" the RPMs, which also results in a lost life. Successfully completing a course without crashing or running out of fuel rewards the player with a bonus life, encouraging efficient driving.
The game distinguishes itself by offering two distinct competitive modes: racing strictly against the clock (time trial) or directly challenging a computer-controlled opponent. This dual approach caters to both time-trial enthusiasts seeking personal bests and those desiring direct head-to-head competition.
A persistent threat on every course is the presence of police vehicles. If the player exceeds the posted speed limit when encountering an officer, a pursuit is initiated. While being forced to pull over and receive a ticket does not cost a life, it imposes a substantial time penalty, making careful speed management crucial for achieving competitive times. A direct collision with a police car results in an instant game over, regardless of remaining lives.
Players can mitigate pursuit risks by slowing down preemptively or by utilizing the standard equipment in all vehicles: a radar detector, which aids in anticipating police presence.
This title functions as a main game experience. While the core experience is complete, the title has been supported post-launch with four distinct downloadable content packages available for expansion.
